research Thyrotropin releasing hormone (TRH): a new player in human hair‐growth control
TRH stimulates human hair growth and extends the hair growth phase.
research Low sex-hormone binding globulin levels in young women with diffuse hair loss
Young women with diffuse hair loss may have low SHBG levels, which could lead to more active testosterone and contribute to their hair loss.
research Thyrotropin-releasing hormone and oestrogen differentially regulate prolactin and prolactin receptor expression in female human skin and hair follicles in vitro
Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.
research Oxidative stress in ageing of hair
Oxidative stress contributes to hair graying and loss as we age.
research Stress-sensing in the human greying hair follicle: Ataxia Telangiectasia Mutated (ATM) depletion in hair bulb melanocytes in canities-prone scalp
Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.
research Irradiation-induced hair graying in mice: an experimental model to evaluate the effectiveness of interventions targeting oxidative stress, DNA damage prevention, and cellular senescence
Using radiation to make mice's hair turn gray helps study and find ways to prevent or reverse hair graying.
research Stress, Hair Growth Control, and the Neuro-Endocrine-Immune Connection
Stress may affect hair growth by influencing hair follicle development and could contribute to hair loss.
research Biology of Hair Growth and Influence of External Factors (Ecology, Stress, Nutrition
External factors like pollution, stress, and poor nutrition can negatively affect hair growth.
research Topical minoxidil counteracts stress-induced hair growth inhibition in mice
Minoxidil helps prevent stress-caused hair loss in mice.
research Role of Insulin Resistance and Oxidative Stress in Hair Loss
Oxidative stress, not insulin resistance, is linked to diffuse hair loss.
research The Effect of Parathyroid Hormones on Hair Follicle Physiology: Implications for Treatment of Chemotherapy-Induced Alopecia
Parathyroid hormones are important for hair growth, but their use in treating hair loss from chemotherapy is still uncertain.
research Foot shock stress prolongs the telogen stage of the spontaneous hair cycle in a non‐depilated mouse model
Stress in mice delays hair growth and treatments blocking substance P can partly reverse this effect.
research Mast cell deficient and neurokinin-1 receptor knockout mice are protected from stress-induced hair growth inhibition
Certain mice without specific receptors or mast cells don't lose hair from stress.
research Stress Inhibits Hair Growth in Mice by Induction of Premature Catagen Development and Deleterious Perifollicular Inflammatory Events via Neuropeptide Substance P-Dependent Pathways
Stress stops hair growth in mice by causing early hair growth phase end and harmful inflammation through a specific nerve-related pathway.
research Chronic Restraint Stress Inhibits Hair Growth via Substance P Mediated by Reactive Oxygen Species in Mice
Chronic stress can cause hair loss by increasing oxidative stress, but antioxidants may help.
research Immunoregulatory mechanisms and stress hormones in psoriasis (part 1)
Stress hormones like cortisol may trigger psoriasis flare-ups.
research The impact of oxidative stress on hair
Oxidative stress damages hair and contributes to aging, and managing it can help maintain hair health.
research Relations between sex hormone level and characters of hair and skin in healthy young men
Higher androgen levels do not cause baldness in men.
research Role of genetics and sex steroid hormones in male androgenetic alopecia and female pattern hair loss: An update of what we now know
Genetics and hormones play a role in male and female hair loss, but more research is needed to fully understand it.
research Neurogenic Inflammation in Stress-Induced Termination of Murine Hair Growth Is Promoted by Nerve Growth Factor
Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.
research Human scalp hair: Modulation by various factors and hormones do estrogens inhibit or stimulate—A perplexing perspective
The effects of estrogen on human scalp hair growth are unclear and need more research.
research Hormonal activity in commonly used Black hair care products: evaluating hormone disruption as a plausible contribution to health disparities
Common Black hair care products may affect hormone levels and potentially impact health, especially in reproductive and metabolic areas.
research SbbHLH85, a bHLH Member, Modulates Resilience to Salt Stress By Regulating Root Hair Growth in Sweet Sorghum
The SbbHLH85 protein helps sweet sorghum grow more root hairs but makes the plant more sensitive to salt.
research Endogenous steroid hormones in hair: Investigations on different hair types, pigmentation effects and correlation to nails
Body hair isn't a good substitute for scalp hair in steroid analysis.
research Quantitative Analysis of Selected Circulating Hematological Biomarkers, Essential Minerals, Vitamins, and Thyroid Hormones in Females Affected by Hair Loss
Women with hair loss often have deficiencies in iron, vitamins, minerals, and lower thyroid function, suggesting the need for nutritional and hormonal treatment.
research Multifunctional nanomedicine targeting the 'seed-and-soil' of hair follicles via simultaneous alleviation of oxidative stress and activation of autophagy for androgenetic alopecia therapy
TFC-loaded microneedles effectively promote hair regrowth in androgenetic alopecia.
research Evaluation of the relationship of digital phototrichogram findings of patients with diffuse hair loss with blood TSH, ferritin and vitamin B12 levels
Low ferritin levels are linked to increased hair loss; no link found between vitamin B12, TSH levels, and hair loss.
research A neuroendocrinological perspective on human hair follicle pigmentation
Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.
research Association Between Hair Diseases and COVID-19 Pandemic-Related Stress: A Cross-Sectional Study Analysis
